What is the required action for visitor access during non-CIP Exceptional Circumstances?

During non-CIP Exceptional Circumstances, the required action for visitor access is to enforce continuous escorted access. This requirement is central to maintaining the security and integrity of Critical Infrastructure Protection (CIP) facilities. Continuous escorted access ensures that all visitors are monitored at all times, which significantly reduces the risk of unauthorized actions or access to sensitive areas within the facility.

By having a designated escort, organizations can maintain awareness of visitor activities, ensuring they adhere to established protocols and do not compromise security. This measure is critical for protecting the infrastructure, sensitive data, and personnel while still allowing for the necessary interactions with authorized visitors for operational purposes.

In this context, other options do not align with the CIP standards for managing visitor access, which emphasizes security through supervision and control mechanisms.
